It features a 7-inch round collar mounted on a rectangular sheet metal base, providing a secure, fixed-position connection point for round branch runs. The fixed geometry eliminates the adjustability found on offset-style fittings, making it a straightforward choice where a straight top connection is the correct application. Fabricated from metal, this fitting is suited for residential and light commercial ductwork installations where consistent airflow distribution and a rigid connection are required.\u003c\/p\u003e\n\u003cp\u003eThis takeoff is used where a round branch duct departs from the top of a rectangular main trunk. Typical applications include residential forced-air heating and cooling systems and light commercial supply duct layouts. The 7-inch collar size suits common branch duct runs serving individual zones or supply registers. Installation is performed by HVAC sheet metal mechanics or duct installers during new construction or system retrofit work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch round collar for direct connection to 7-inch round branch duct\u003c\/li\u003e\n  \u003cli\u003eNon-adjustable fixed design for straight top takeoff applications\u003c\/li\u003e\n  \u003cli\u003eRectangular base attaches flush to the top of a rectangular main trunk\u003c\/li\u003e\n  \u003cli\u003eSheet metal construction for durability in forced-air duct systems\u003c\/li\u003e\n  \u003cli\u003eSuitable for residential and light commercial HVAC installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for 7-inch round branch duct connections on rectangular main trunk ductwork in residential and light commercial forced-air HVAC systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified HVAC technicians or sheet metal mechanics. Power down the air handling system before cutting into or modifying any section of the duct trunk. Secure the rectangular base to the trunk using sheet metal screws and seal all joints with UL 181-rated foil tape or mastic sealant per applicable mechanical code requirements. Do not attempt to force or modify the fixed collar angle, as this fitting is designed for straight top takeoff connections only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Size\u003c\/strong\u003e: 7 inches round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSub Type\u003c\/strong\u003e: Non-Adjustable Duct Takeoff\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: HVAC Duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer\u003c\/strong\u003e: Lukjan Metal Products\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LUKJAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: to5107\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LUKJAN","offers":[{"title":"Default Title","offer_id":51620773101874,"sku":"TO5107","price":20.89,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/592e0f0ea636c94c6b99b81a613eb3ac_2dbae237-966e-4de9-9ac0-68c1efb2849b.jpg?v=1787346265","url":"https:\/\/voomisupply.com\/products\/lukjan-to5107-non-adjustable-metal-top-takeoff-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
